Guam Accelerates The Move To Renewables

U.S. Territory Overview

The Territory of Guam  is an organized, unincorporated territory of the United States located in the western Pacific Ocean. The population of Guam is approximately 0.17 million people.

In 2021, Guam’s economy was ranked 211th in the world in gross domestic product (GDP). The country’s economy is dependent on tourism and the export of scrap iron, scrap copper, construction vehicles, trunks, cases, and rubber.

Environmental Policies

In 2008, Guam enacted a Renewable Energy Portfolio Standard, requiring the government-owned electric utility, Guam Power Authority to sell 8% of the territory’s electricity from renewable energy sources by 2020, 10% by 2025, and 25% by 2035.

In 2016, the United States and territories like Guam, Puerto Rico and American Samoa signed the Paris Climate Agreement, committing to a 26% domestic reduction in greenhouse gases by 2025, compared to 2005.

In 2017, President Donald Trump announced that the U.S. would cease all participation in the 2015 Paris Climate Agreement. The United States formerly withdrew from the Paris Agreement on November 4, 2020.

In 2019, Guam revised the territory’s Renewable Energy Portfolio Standard, requiring the GPA to sell 50% of the territory’s electricity from renewable energy sources by 2035 and 100% by 2045.

In 2021, President Joe Biden announced that the U.S. would officially rejoin the Paris Climate Agreement. The United States formerly rejoined the Paris Agreement on February 19, 2021.

Power Generation Capabilities

In 2021, 100% of the people in Guam had access to electricity. In 2021, the government-owned electric utility, Guam Power Authority used refined petroleum (95.6 %) and renewable energy (4.4 %) to generate electricity on the island territory. Solar is the dominant type of renewable energy used to generate electricity in Guam.

Renewable energy developments in Guam include:

  • 60 MW Solar Project – In June 2022, Korea Electric Power Corporation commissioned the Mangilao Solar Photovoltaic Park 1project at a site on the eastern area of the island.
  • 6 Solar Project – In July 2022, New York renewable energy company, Clean Capital acquired the Dandan solar project, which was commissioned in October 2015. The solar project is located on the southeastern area of the island of Guam.
  • Ocean Energy System Project – In January 2023, S. Department of Energy (DOE) awarded a research grant to the University of Guam to explore the potential for ocean energy systems on the island.


Guam imports refined petroleum for power generation and transportation. In 2021, Guam imported U.S.$507 Million of refined petroleum.

On 24 February 2022, Russia invaded Ukraine, prompting the European Union, United Kingdom, United States, Canada, Japan, South Korea, Australia, and New Zealand to place economic sanctions on Russian imports and exports. As a result, the crude oil and natural gas prices increased by over 50% from May 2021 to May 2022.

Guam has significant undeveloped renewable energy resources, including solar, offshore wind, onshore wind, wave energy, and biomass. Guam’s renewable energy resource potential could meet all of the territory’s power requirements. Volatile oil prices have prompted Guam to actively develop new renewable energy projects.
